The impressive book presented here is devoted to the snake species of the Lao People’s Democratic Republic, or, more simply, Laos. Located at the heart of the Indochinese Peninsula, a major hotspot of tropical biodiversity, Laos is the only landlocked country in Southeast Asia. In fact, the present book also covers many species of the adjacent countries, such as Thailand, Cambodia, Vietnam and the Chinese province of Yunnan. Many discussions on the systematics and nomenclature of various genera and species have thus bearings on the reptile fauna of the whole of South-east Asia.
